A Study on Natural Clay and Moringa Oleifera for Sustainability of Landfill Liners

Abstract

This project aims to characterize the municipal solid waste leachate, using column study method to evaluate the concentrations of constituents present in landfill leachate. The leachate sample were tested for several physical and chemical parameters. The initial results demonstrated that the characterizations of leachate found to be highest range of contamination. Hence compacted clay liner is used in this treatment. Moringa Oleifera is added with compacted natural clay to retain the constituents in the liner. Compacted natural clay liner shows the removal efficiency of TDS, Sodium and Potassium is 88.44%, 90.6% and 68.46% respectively. Moringa Oleifera with Compacted natural clay liner shows the removal efficiency of TDS, Sodium and Potassium is 90.2%, 98.75% and 81.2% respectively. Result shows Moringa Oleifera with Compacted clay liner has been an effective for the removal of constitutes present in landfill leachate.
